Title: Manufacture of magnet generator
Inventor: OSAWA YUJI
IPC: H02K21/22
Filed: 1987-03-18
Abstract: PURPOSE:To contrive to improve productivity and mechanical reliability and enable reduction of manufacturing cost by shearing and processing parts of thickness in the outer periphery of a rotor along the axial direction of said rotor and by projecting parts thereof. CONSTITUTION:In a permanent-magnet generator for power supply of an internal combustion engine, an ignition signal generator is composed of a magneto coil 12 on a stator side and a protrusion 11 formed on the outer periphery of a flywheel cylinder 5a and generates a control signal for an igniter by their interaction. When said protrusion 11 is formed, the inner part of a place for the protrusion 11 to be formed out of the outer peripheral face of the flywheel cylinder 5a is sheared and processed from the outside (the metal plate 8 side) along the axial direction (direction of the arrow p) of a rotor 6. The sheared part is compressed and projected in the left side end, and shaped to form the protrusion 11. By this means, no force is applied in the circumferential direction of the flywheel 5 and no distortion accompanying such force occurs to improve dimensional accuracy.

Title: Character procession device
Inventor: MASAKI KATSUMI
IPC: G06F17/28
Filed: 1980-05-08
Abstract: PURPOSE:To prevent erroneous conversion and the occurrence of an excessive retrieval time, by regarding second character strings as abnormal division when dividing the first character string into two second character strings when the number of characters in the first character string is a specific number. CONSTITUTION:In case that the first character string such as Kana (Japanese syllabary) is subjected to processings such as conversion to Kanji (Chinese character), English, etc., it is effective that the first character string is processed after it is divided plural second character strings. However, if the first string, for example, '' '' is converted to second character strings ''  '' and ''  '', erroneous Kanji is output or the number of combinations of pertinent Kanji becomes large or much time is spent for retrieval. Consequently, when the overall length of the conversion unit is a specific number (4 in this case), for example, in case of division of ''    '' into ''  '' and ''  '', the flat 0 is stood if this conversion unit is divided into two by a specific number of characters (2 in this case). Abnormal division is detected by checking whether this flag is stood or not.

Title: Method and device for continuous treatment of molten iron
Inventor: ITAYA HIROSHI
IPC: C21B7/14
Filed: 1984-03-30
Abstract: PURPOSE:To treat adequately and continuously a molten iron with high reaction efficiency by streaming down the molten iron into a reaction vessel provided in the mid-way of a molten iron spout and adding a treating agent to the down- flow part of the molten iron while blowing a gas into the vessel from the bottom thereof to generate swirling flow. CONSTITUTION:A molten iron 6 flows down in a molten iron spout 3 and enters a trough-shaped reaction vessel 16 on the down stream after slag 4 is discharged by a skimmer 7. When an inert gas is blown through the blow port 10 in the bottom of the vessel 16, the molten iron 6 is entrained and risen by floating foam until the molten iron flows down 22 near the central part of the vessel 16. Circulating flow 20 is therefore generated within the cross section of the vessel 16. As a result the molten iron 6 flows down in the vessel 16 in the form of swirling flow 19. A powder treating agent such as a desulfurizing agent or the like is accelerated and is added to the down flow 22 from a nozzle 11. The treating agent is effectively incorporated and dispersed into the molten iron 6 by the above-mentioned method, by which the continuous treatment of the molten iron 6 with high reaction efficiency is made possible.

Title: Data transmission system
Inventor: INAGAKI MASAYA
Filed: 1985-03-26
Abstract: PURPOSE:To prevent collision of data by permitting each terminal device to send data after a delay time intrinsic to each terminal when the absence of a signal is detected on a data bus and sending a dummy signal when no transmission data exists on all terminal devices. CONSTITUTION:Plural peripheral devices P1-Pn are connected via data terminal devices DT1-DTn on a common bus 100. The terminal devices DT1-DTn are operated independently with respect to transmission and reception, and the reception section supervises the presence of the signal of the data bus 100. When the absence of a signal on the data bus 100 is detected, the terminal devices DT1-DTn are permitted to send a signal with a delay of an intrinsic time depending on each. Even when all terminal devices obtain the transmission permission, if no data is sent, one of the terminal devices sends dummy data. When a time intrinsic to each terminal device is elapsed after the end of transmission of the dummy data, the transmission is permitted again. Thus, the collision of signals on the data bus is prevented and the effect of a fault occurred in a terminal device onto other terminal devices is prevented.

Abstract: PURPOSE: To achieve the smaller size, higher accuracy and lower cost of an automatic focus detector for camera which performs focus detection by respectively detecting the optical images having gone through two optical paths by using the  photo detectors by disposing these back to back, in said detecotr.  
     CONSTITUTION: Photo detectors 301a and 301b which are disposed back to back are used. More specifically, the optical image going through the optical path on  the right side of the subject is reflected by a stationary mirror 303 and is imaged on the photo detector 301b. On the other hand, the optical image through the optical path on the left side is reflected by a movable mirror 304 and is formed on the photo detector 301a. The output signals from both photo detectors are sent to an electronic circuit 302 and are processed. When the camera is faced toward the subject and its shutter button is pushed in the state when the subject image is formed on the element 301b,the movable mirror 304 starts rotating and at the same time the forcal length of the camera changes. When the outputs of both elements 301a, 301b coincide, the focus to the subject is matched and the shutter is released, whereby photographing is accomplished.

Title: Feedback type amplifier
Inventor: SHIGAKI MASAFUMI
IPC: H03F3/345
Filed: 1983-04-08
Abstract: PURPOSE:To eliminate the need for a capacitor used for a feedback path and to facilitate integration by feeding the output of an inverting circuit consisting of a field effect transistor (FET) back to a terminal through a series circuit of a level shifting circuit and a resistive load circuit. CONSTITUTION:The level shifting circuit 1 consists of an FET13, diodes D1-Dn, and a load 14 for a constant current. The output of the inverting circuit consisting of FETs 11 and 12 is lowered to the same level as the input voltage by the level shifting circuit 1 and then fed back to the input terminal through a resistance R. Therefore, there is no voltage difference between an input and an output terminal, so it is not necessary to provide a DC component cutting capacitor to the feedback path. Further, the extent of voltage shifting by the level shifting circuit 1 depends upon the optimum connection number of diodes D, etc.
